Given numbers are 438, 858, 310, 355

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 310 are 2 x 5 x 31

Prime factors of 355 are 5 x 71

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 438, 858, 310, 355

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(438, 858) = 62634

GCD(438, 858) = ( 438 x 858 ) / 62634

= 438 / 858

= 438

Step2:

LCM(6, 310) = 930

GCD(6, 310) = ( 6 x 310 ) / 930

= 6 / 310

= 6

Step3:

LCM(2, 355) = 710

GCD(2, 355) = ( 2 x 355 ) / 710

= 2 / 355

= 2

So, Greatest Common Divisor of 438, 858, 310, 355 is 1
